LTE-M / NB-IoT

Wireless open / close logger

Wireless open / close sensor detects and logs in its memory events of door opening and closing. If a change of state is detected, the device immediately sends the notification to Efento Cloud or other IoT cloud platform. The device uses magnetic sensor to detect open / close event.

Efento sensors transmit the data over cellular network (Narrowband IoT and LTE-M) and do not require any additional devices (router, gateway, etc.). Sensors are also equipped with Bluetooth Low Energy interface, which allows quick and easy configuration with a smartphone. Efento NB-IoT / LTE-M sensors can be integrated with any cloud platform.

  • Sensor detects open / close events
  • Batteries ensure up to 10 years of maintenance free operation
  • The device sends the data over cellular networks (NB-IoT and LTE-M) to Efento Cloud or any other cloud platform.
  • Sensor's configuration can be changed remotely from the cloud or with a mobile application over Bluetooth Low Energy
  • The device stores 60,000 measurements in its memory, when the memory is full, the oldest measurements are overwritten
